In "The Central Theme of Southern History" (1928), Phillips maintained that the desire to keep their region "a white man's country" united the white southerners for centuries. Phillips' emphasis on race was overshadowed in the late 1920s and 1930s by the Beardian interpretation of Charles Beard and Mary Beard, who in their enormously successful
The Rise of American Civilization (1927) emphasized class conflict and downplayed slavery and race relations as a cause of the American Civil War. By the 1950s, however, the Beardian economic determinism was out of fashion, and the emphasis on race (rather than region or class) became a major topic in historiography.
By 2000, and citing Phillips, Jane Dailey, Glenda Gilmore, and Bryant Simon argue:
- "The ways in which white southerners "met" the race "problem" have intrigued historians writing about post-Civil War southern politics since at least 1928, when Ulrich B. Phillips pronounced race relations the "central theme" of southern history. What contemporaries referred to as "the race question" may be phrased more bluntly today as the struggle for white domination. Establishing and maintaining this domination--creating the system of racial segregation and African American disfranchisement known as Jim Crow--has remained a preoccupation of southern historians."
In his review of
Complicity: How the North Promoted, Prolonged, and Profited From SlaveryBy Anne Farrow, Joel Lang and Jenifer Frank, the historian Ira Berlin wrote, "Slavery in the North, like its counterpart in the South, was a brutal, violent relationship that fostered white supremacy.
Complicity 's authors shred the notion, famously advanced by the Yale historian U.B. Phillips, that the central theme of Southern history was the region's desire to remain a white man's country. Phillips was not so much wrong about the centrality of white supremacy to the South as blind to its presence in the North."
